E-Cat Test Demonstrates Energy Loss

Promoter Andrea Rossi’s most recent test of his “energy catalyzer” failed to demonstrate the production of excess heat.

On Oct. 7, “the ‘E-cat’ invented by Andrea Rossi ran in a completely stable self-sustained mode for over three hours,” journalist Mats Lewan of Ny Teknik wrote.

According to Lewan, Rossi’s device released an average of 2.5 kilowatts of heat in 3.5 hours. This amounts to 31.5 megaJoules of energy.

However, Rossi heated the device with 2.7 kilowatts of electricity for four hours in advance. This amounts to 38.88 megaJoules of energy. He also heated the device during the phase which Lewan called “self-sustaining.” The input was 115 Watts for 3.5 hours. That’s 1.44 megaJoules of energy.

Let’s do the math of the total energy input versus energy output: (38.88 + 1.44) – 31.5 = 8.82.

That’s a total energy loss of 8.82 MJ during a 7.5-hour period*. In other words, Rossi has demonstrated a water heater that is 78 percent efficient. This is inconsistent with his claims of having a device that produces substantial amounts of excess heat in comparison to input energy.

On Oct. 7, New Energy Times asked Lewan how he justified his and Rossi’s implication that the Oct. 6 experiment showed a net energy gain, as well as their claim that the device was self-sustaining.

“I don’t believe I claimed anything at all,” Lewan wrote. “And I don’t think I reported a net energy gain. I only reported the energy developed during self- sustained mode.”

These are glaring inconsistencies.

Furthermore, in his technical report, Lewan ignores the input energy from the first four-hour warm-up period.

“The E-cat was considered to be completely operating only after reaching self-sustained mode,” he wrote.

Lewan’s and Rossi’s choice to ignore the input energy from the four-hour warm-up period is like saying a sailplane can fly without power, so long as it is first carried aloft by a tow plane.
